         command when the printer connection is re-opened and before
         printing begins.

      4. Password Protection

         This option allows a password to be supplied when a terminal is
         signed on, preventing unauthorized use of the terminal ID.

      5. Suppression of Punch Separator and Large Letters.

         This option suppresses both separator cards which RJS normally
         puts in front of each punched output deck, and separator pages
         on printed output containing the job name in large block
         letters.  These separators are an operational aid when the
         ouptut is directed to a real printer or punch, but generally
         undesirable for an ARPA user who is saving the output in a file
         for on-line examination.

NIC 20854, RFC 599:  Update on NETRJS



F.  WARNING ON TENEX NETRJS USER PROCESS (6)

   The Tenex implementation of NETRJS user program is a command normally
   called "RJS".  This program has some pitfalls of which users should
   be aware.

      1.  For strictly historical reasons, the commonly-available
          version of the Tenex RJS command uses Socket 15, and
          therefore, the ASCII-63 translation.  We hope to propagate
          soon a version which uses the ASCII-68 mapping via Socket 73,
          and stamp out the earlier version.

      2.  The Tenex RJS command fails to recognize the US character
          sometimes used instead of CR LF as end-of-line.  As noted in
          RFC 571, the Tenex user FTP program has the same problem.

      3.  The Tenex RJS command truncates without warning card images
          exceeding 80 characters in length.

G.  REFERENCES ON NETRJS

   1. "Interim NETRJS Specifications", R. T. Braden.  RFC #189:  NIC
      #7133, July 15, 1971.

      This is the basic system programmer's definition document, and is
      really the final specification.  The proposed changes mentioned on
      the first page of RFC #189 were never implemented, since the DTP
      then in vogue became obsolete.

   2. "NETRJS Remote Operator Commands", R. T. Braden.  NIC #7182,
      August 9, 1971

      This document together with References 3 and 8 define the remote
      operator (i.e. user) command language for NETRJS, and form the
      basic user documentation for NETRJS at CCN.

   3. "Implementation of a Remote Job Service", V. Martin and T. W.
      Springer.  NIC #7183, July, 1971.

   4. "Remote Job Entry to CCN via UCLA Sigma 7; A scenario", UCLA/CCN.
      NIC #7748, November 15, 1971.

      This document described the first NETRJS user implementation
      available on a server host.  This program is no longer of general
      interest.

   5. "Using Network Remote Job Entry", E. F. Harslem.  RFC #307:  NIC
      #9258, February 24, 1972.

      This document is out of date, but describes generally the Tenex
      NETRJS user process "RJS".

   6. "EBCDIC/ASCII Mapping for Network RJS", R. T. Braden.  RFC #338:
       NIC #9931, May 17, 1972.

      The ASCII-63 mapping described here is no longer correct, but
      CCN's standard ASCII-68/EBCDIC mapping is described correctly.

   7. "NETRJT--Remote Job Service Protocol for TIP's", R. T. Braden.
      RFC #283: NIC 38165, December 20, 1971.

      This was an attempt to define an rje protocol to handle TIPs.
      Although NETRJT was never implemented, many of its features are
      incorporated in the current Network standard RJE protocol.

FIGURE 1.  NETRJS CHARACTER MAPPINGS AT UCLA-CCN

   The character set of the VRBT (VIRTUAL Remote Batch Terminal) is
   determined by the initial connection to RJS, as follows:

      VRBT Character Set  |  ICP Socket    OR    Server Telnet Command
      ----------------------------------------------------------------
         EBCDIC           |      71         |          RJS
         ASCII-68         |      73         |          ARJS
         ASCII-63(tty)    |      75         |          TTYRJS

   These mappings are as follows:

      ASCII-68 Mapping:

         Corresponding graphics are mapped one-to-one.

         Unmatched graphics are mapped as in the table below.

         ASCII-68 controls are mapped one-to-one onto the matching
         EBCDIC controls, with DC4(ASCII) mapped onto TM(EBCDIC).

      ASCII-63 Mapping:

         Corresponding graphics are mapped one-to-one.

         ASCII codes X'61' - X'7A' (the ASCII-68 lower case letters are
         mapped onto EBCDIC lower case.

         Unmatched graphics are mapped as shown in the table below.

         ASCII-63 controls X'00' - X'1F' are mapped as for ASCII-68.

         ASCII codes X'60' and X'7B' - X'7E' are mapped as shown in the
         following table.
